Flow Path Excitation Mechanisms for Turbomachine Blades,scribed, with details of analytical contributions to these areas. Experimental procedures for measurements of blade non-steady forces in the laboratory and in the field are described. Selected test data are included. Recent developments using the rotating water table approach are reviewed.

An Improved Procedure for Component Life Estimation with Applications,ue failure, but it is also suitable for the design of new components. The procedure incorporates the effects of steady stresses, dynamic stresses from excitation spectra, and material cyclic properties. The Rainflow Cycle Counting procedure is used to incorporate complex response waveforms, and the

Stability of Rotors, information about the parameters influencing the stability. This chapter treats the special system of a rigid rotor, running in two oil film bearings. The equations of motion are derived and the stability behavior is evaluated by means of the complex eigenvalues. Analysis results show a good correlation with measurement results from a test rig.

The Diagnosis and Correction of Steam Turbine Blade Problems, propagation cycles. Four case histories of turbine blade failure are presented in detail, with operating conditions, diagnostic procedures used to determine failure cause, and the remedies chosen to avoid further blading failures. Thirteen references to the subject literature are included.
